The Supalai River Place is probably one of the best locations you would find in Bangkok. Located on 22nd floor of a posh apartment, it offers breath taking view of the river and Bangkok high rises. The apartment is extremely well maintained with swimming pool, gym, laundry and restaurant facilities. You can ask for local taxi at the reception and security guard will get one arranged in no time. The extremely efficient 24x7 security at the apartment makes your stay a pleasant one.
Dirk has been a very kind host and was extremely helpful in every sense. He's very approachable and will go extra mile to address your concerns.
In a nutshell, if you are traveling to Bangkok please do not give a second thought while blocking this place. I am sure you will also be pleasantly surprised with its great hospitality!
